The study of the physical features (external structure) of plants is referred to as morphology. Morphology of legumes is not just a biological pursuit but can aid in many everyday decisions for the forage manager. Legumes, whether annual, biennial, or perennial, are plants bearing pods (containing one to many seeds) which dehisce (split open) along both dorsal and ventral sutures.
